“Allegheny Technologies Incorporated (ATI),one of the largest steel plant in the world  and extraction technology in Pittsburgh” It was the first visit by MHMHD to talk with famous company and get some experiences.visit ATI “We feel at home from this visiting”

“It was really excited. They can meet us, and we can get some experiences from them,  we must get some cooperation from this conversation,” says by MHMHD president and Marketing Director Jerry Deng.” In this meeting, ATI real understand what company we are. For us that was a real win. CLEAR SLAG POT



Although the MHMHD is a privately held enterprise, We strive to the development of the company. We are wholehearted to talk with our customers to get some cooperation. We always believe that: believe in yourself, I can do it.

What Is a Roller Mill?

Roller mills are industrial machines that are used to break down and process an assortment of ingredients and materials. Roller mills are used in a variety of industries.

Unlike traditional windmills and grain mills, which use large stones to grind and break down ingredients into powder, industrial roller mills function by crushing and grinding materials between two large rollers. The rollers compress the materials in the same way that a steamroller would, reducing the materials to pulp and powder.

Roller mills have a variety of uses in an assortment of industries. The mills have traditionally been used in agricultural industries, crushing grains to create various grades of flour. The construction industry also has put the vertical roller mill to good use, using the mills to crush gravel into smaller rocks and powder for paving and construction.

Apart from being able to grind the various materials faster than a traditional stone grinding mill, roller mills have the advantage of a larger surface area to apply to grinding. This larger surface area allows more material to be ground at once, which makes the process even faster.

How to Install or Debug a Vibrating Feeder?

The vibrating feeder consists of vibrating frame, spring, vibrator, motor vibrating device and motor. The vibrator is made of two fixed eccentric shafts whose gears are jogged. When installation, the two gears must be jogged according to the sign. Through drive of the motor, the two eccentric shafts start rotating to produce a linear huge power which forces the feeder to vibrate. Through the vibration, the materials will slip and sling on the funnel, moving forward, when the materials pass the screening part, smaller parts will fall down, and avoiding the further crushing, so screening purpose can be reached.

How to Install or Debug a vibrating feeder?

The vibrating feeder can be offered after assembled and trial operation by our factory. The customers should check the machine after receiving it so as to make sure whether some problems appear during the transportation. When installation, debugging and trial operation, please pay attention:

1. Since the vibration of the feeder is heavy, it’s better to install the machine on concrete base. The height, depth and size of the base should be calculated according to the earth conditions. The weight of the base should be 1.5 times that of the machine. The installation size refers to the diagram. The height of the base and the discharging form can adopt steel structure or concrete platform according to the earth conditions to meet the need of the next working procedure. (according to customers’ requirement)
2. The discharging glide groove of the feeder belongs to addictive fixed device of the machine. It should be kept 90mm away from the feeder in vertical direction, and 30mm in horizontal direction.
3. When installing the motor and supporting frame, the central line and horizontal line of the wheel of the motor and the vibrator should form a degree of 45. The supporting plate and the supporting base of the motor should form a degree of 15-20. And the rotating direction of the vibrator should also be considered.
4. Clean the anti-dust oil in the vibrator and add lubrication oil. The type of the oil refers to 1(1) in No.7. the level of the oil is higher than the height of the mark.
5. after installation and debugging, try the trial operation. During the no-loading trial operation, pay attention: (1) lasting for 2 hours without stop; (2) all the firmware is fastened well; (3) there is no abrasion, crump, rubbing and abnormal noise; (4) the vibration is stable.
6. there are other requirement besides the above: (1) when putting the raw materials into the feeder, do not impact the funnel, do not put materials in one side or over put raw materials to avoid damaging the machine, supporting spring and affecting the vibration of he machine; (2) the max feeding size should be up to standard.

Vibrating Feeder Lubrication and Safety Technology

The vibrating feeder is manufactured on the theory of vibration, which is widely used in mining, construction materials, silicate and chemical industry. It can provide ores and rocks within 500mm for the next working procedure.

Maintain and examine the machine frequently to prolong the service life of the machine, which is an important way to assure normal operation. The customers must notice this.

As to the lubrication, the following points should be pay attention to: Oil applied in this machine should be wartery. The lubricating oil should adapt to the local environment and temperature. Usually 20# is adopted. make sure the level of the oil in the vibrator is higher than the sign. Change the oil every 3-6 months. Clean the oil tank, bearing track and gear surface with gasoline or coal oil before changing.

Safe technology: the operator must be trained about safety technology; during operation, no person is allowed stand by the machine. No hand touching, adjusting and checking. the machine should touch the earth. The wire must be reliably insulate and wrapped in snakeskin bags. Check frequently whether the wire is abraded or creepage.

How vibrating feeder Works?

There are two eccentric shafts rotating at high speed at the same time from opposite directions, thus the strong centrifugal force is formed. The component forces of centrifugal force along the vibrating direction will always overlap each other, then counteract with that of vertical force from vibrating direction, then exciting force along single direction is formed to drive the feeder vibrate along straight line. When materials are fed into the feeder, they may be thrown up and move like Para curve, then fall down. The materials will move forward on the slope surface of the feeder.
